Efficient calibration of contact-less resonant bio-sensor affected by operating conditions
Résumé
In this paper, a new model-based method is presented for the development of calibration technique of inductively coupled biosensors. This method is applied to the case of a lens-based intra-ocular pressure sensor. A new performance indicator is proposed. It is the 2 nd-order coefficient of the single-variable quadratic polynomial regression approximating the Bode phase plot of the system. This new indicator is reliable to significant distance and angle variations between primary and secondary and to small signal-to-noise-ratio.
